About the Isham Conservation Area
The Isham Conservation Area covers about 9.6 hectares within North Northamptonshire Council’s area. Inside the boundary are 23 listed buildings (1 Grade II*, 22 Grade II). The most significant is Church of St Peter, Grade II*. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
